6 DISTRIBUTION OF RADIOHELIOGRAPHS IN THE WORLD.
7 Location: INPE s campus at Cachoeira Paulista (Longitude 45 o 0 20 W Latitude 22 o S). Configuration: T shaped array consisting of 38 parabolic antennas of 4 m diameter, with the longest baseline of about of 2.3 km (East- West) and 1.2 km (South). The central portion have 26 antennas distributed in a compact T, with base lines up to 252 m (E-W) and 162 m (S). Spatial and time resolutions: < 10 sec of arc at 5.6 GHz and 100 ms. Frequency: , 2.8 and 5.6 GHz. Sensitivity: 3 mjy at 21 cm for a system temperature of 50 K, using low noise amplifiers.

14 BDA will produce high spatial and time resolution images of radio sources with high dynamic range. BDA will provide solar radio images in the lower corona where energy release to solar flare takes place, their analysis will lead to better understanding of the fundamental problems in solar physics and also will be used, in a spectral tomography technique being developed for application to space weather forecasting. BDA will be very useful for galactic and extra galactic investigations of the southern sky not accessible to VLA.

17 Coronal holes are important large scale structures on the Sun, which produce high speed solar wind streams (HSS). Interaction of Solar Wind with magnetosphere produces Geomagnetic storms that are known for for producing MeV electrons in Earth s magnetosphere. These electrons can be hazardous to satellites and astronauts in the space, and hence important for space weather prediction. BDA can observe the coronal holes at multi frequenies.
